IMPROVEMENT IN STOP-VALVES FOR CASKS AND OTHER VESSE LS.

Specification forming part of Letters Patent No. 157,628, dated December8, 1874; application filed October 9, 1874.

To all whom it may concern:

Be it known that I, WILLIAM MORGEN- STERN, of the city, county, andState of New York, have invented a certain new and useful Improvement inStop-Valves for Oasks and other Vessels, of which the following is aspecification:

This invention .is illustrated in the accompanying drawing, in whichFigure 1 represents a front view. Fig. 2 is a longitudinal verticalsection. Fig.3 is a section of the valve-chamber in a plane parallel tothe motion of the valve.

Similar letters indicate corresponding parts.

This invention consists in a valve-chamber, which communicates, througha hole in its bottom plate, with the interior of the cask or vessel, andwhich contains a valve that works against a packing-ring secured in agroove in the bottom plate, and against another packing-ring secured inthe face-plate of the valve-chamber, the valve and the face-plate beingprovided with holes in such a manner that by turning the valve the holesin the bottom and face plates of the chamber and that in the valve canbe made to coincide, and the contents of the cask or vessel are free todischarge.

In the drawing, the letter A designates a chamber, which is made ofbrass, iron, or other suitable material, and which is so formed that itcan be readily secured to the tap-hole of a cask or barrel, or to thedischargeopening of any other vessel from which liquid is to be drawn.The face-plate a of this chamber is detachable from its body, beingfastened to the same by screws, or any other suitable means, and in thebottom plate I) of said chamber is a hole, 0, which communicates withthe interior of the cask or vessel. This hole is surrounded by acircular groove, which 0011- tains a packing-ring, d, and in theface-plate a is also a hole, 0, in line with the hole 0, and surroundedby a circular groove, which contains a packing-ring, f. Between the faceand bottom plates of the valve-chamber is situated the valve B, thefaces of which are flat, and work against the packing-rings elf. Saidvalve is secured to a pivot, g, which turns in the face and bottomplates of the valve-chamber, and which is provided with a head ofsuitable shape to receive a wrench, for the purpose of turning thevalve.In the said valve is a hole, It, and if the valve is turned to theposition shown in Fig. 2 this hole coincides with the holes 0 e in thevalve-chamber, and the liquid from the vessel is free to discharge.

By tightening up the face-plate of the valvechamber the faces of thevalve are caused to work tight against the packing-rings tlf, andleakage past the said faces is prevented.

In the face-plate is a cam-shaped dovetailed recess, t, which isintended to receive the faucet G. This faucet is provided with awedgeshaped bottom flange, j, and with a nipple, k, which fits the hole6 in the face-plate of the valve-chamber. Bound this nipple is placed apacking-ring, l, and if said nipple is inserted into the hole 6, and theflange j is turned so that it catches in the canrshaped recess 2', thepacking-ring l is pressed up tight against the face-plate, and a tightjoint is produced. At the same time the faucet is firmly retained inposition.

My valve is intended to be permanently secured to a cask or barrel, andas long as said valve is closed no liquid can discharge. 1f the barrelis to be tapped, the faucet G is secured inposition and the valve isopened.

By turning the faucet in the proper direction the liquid is permitted todischarge. If desired, the valve can be closed and the faucet removed.

If the faucet is opened, the bung of the cask must be opened, so as toadmit air, and it is desirable to construct said bung so that it can bereadily opened and closed by means of the same key which serves tooperate the valve B.

By this arrangement the barrels or casks are preserved against injuryfrom blows of a hammer,'and the operation of tapping can be effectedwith ease and facility.

What I claim as new, and desire to secure by Letters Patent, is

The valve-chain ber A, provided with packing-rings cl f and holes 0 c,in combination with a that valve, B, working between said packingrings,and pro ided with a hole, h, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this3d day of October, 1874:-

WILLIAM MOBGENSTERN.
